Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a process testing device for the spacing of transformer cores. Background Technology

[0002] In existing technologies, transformer core spacing detection mostly employs manual measurement or fixed optical inspection. Manual measurement uses contact tools such as calipers and feeler gauges, which is inefficient, its accuracy is greatly affected by human factors, and it easily scratches the core surface, affecting insulation performance. In fixed optical inspection, the camera angle is fixed, and it can only be aimed in a single direction, making it difficult to reach inside the core window to comprehensively inspect the inner walls and outer surface of the core, resulting in blind spots. The core window is relatively deep and has many inner wall surfaces, making it difficult for a single fixed viewing angle to cover the entire inspection area, while multi-camera solutions lead to increased costs, cumbersome calibration, and difficulties in synchronization. In addition, the presence of metal dust at the core processing site easily contaminates the laser measuring instrument lens and optical window, causing laser energy attenuation, spot distortion, measurement drift, or even loss of readings, requiring frequent shutdowns for cleaning, which seriously affects inspection efficiency. Summary of the Invention

A protrusion is installed at the intersection of the reciprocating guide grooves. A guide groove is opened on the inner side of the protrusion. A protrusion is installed at two corner positions on one side of the reciprocating guide groove.

[0005] Preferably, the stabilizing component includes a circular groove 1 formed inside the switching rod, a guide shaft movably disposed inside the circular groove 1, a spring 1 fixedly disposed between the guide shaft and the inner wall of the circular groove 1, and four sets of circular grooves 2 formed inside the lower side of the guide shaft, each of the four sets of circular grooves 2 having an inclined guide shaft movably disposed inside, and a spring 2 fixedly disposed between the inclined guide shaft and the inner wall of the circular groove 2.

[0006] Preferably, the cleaning mechanism includes two sets of fixing blocks fixedly disposed on the same side of the mounting cylinder at upper and lower positions. A rotating shaft is movably disposed on the inner side of each of the two sets of fixing blocks. A ratchet is fixedly disposed on the outer side of each of the two sets of rotating shafts. A torsion spring is sleeved on the outer side of each of the two sets of rotating shafts. A connecting frame is fixedly disposed on the outer side of each of the two sets of rotating shafts. A connecting rod is fixedly disposed on one side of the connecting frame. A vacuum tube is fixedly disposed on the inner side of the connecting rod. A rack is fixedly disposed at both ends of the switching rod.

[0007] Preferably, the hydraulic cylinder telescopic rod is fixedly connected to the drive rod, the connection between the disc and the switching rod is adapted to the corresponding movable port, and one side of the guide cylinder passes through the interior of the mounting cylinder and is connected to the mounting frame.

[0008] Preferably, the two sets of laser measuring instruments are mirror-symmetrically arranged, and the protrusions and the two sets of protrusions are arranged to protrude in the reciprocating guide groove.

[0009] Preferably, the guide shaft is inserted into and adapted to the reciprocating guide groove, the four sets of inclined guide shafts are arranged crosswise on the lower side, corresponding to and adapted to the crosswise guide groove, and the second spring is in a compressed state.

[0010] Preferably, the two sets of cleaning mechanisms are arranged in a mirror-symmetrical manner, the rotating shaft moves through the ratchet housing and is fixedly connected to the internal gear, and the rotating shaft is fixedly connected to the connecting frame.

[0011] Preferably, the ratchet housing is fixedly provided with a gear ring, the outer gear ring of the ratchet is adapted to the rack, the upper and lower ends of the torsion spring are respectively inserted into the fixing block and the connecting frame, and the dust collection tube is aligned with a position of the laser measuring instrument along the rotation trajectory of the fixing block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The electric gantry frame drives the lifting frame to move downward, aligning the telescopic mechanism with the window of the iron core. Then, it enters the iron core and uses two sets of laser measuring instruments to inspect the inner wall of the iron core. After passing through the iron core, the hydraulic cylinder pushes the drive rod to move axially along the sleeve and mounting cylinder. The drive rod drives the disc to move forward, and the disc drives the switching rod and the movable port to slide in a direction on the mounting cylinder. At the same time, the spring is compressed, and the guide shaft slides in the reciprocating guide groove, thereby rotating the guide cylinder, the mounting frame, and the laser measuring instrument 1 by 90 degrees. The synchronous measurement of the distance between the inner walls on both sides of the window can be completed in one insertion, avoiding the reference conversion error caused by repeated measurements on one side. The two sets of laser measuring instruments are arranged symmetrically in a mirror, and the data on both sides are in the same coordinate system and can be directly compared, which significantly improves efficiency and consistency.

[0013] 2. When the guide shaft passes the protrusion at the intersection of the reciprocating guide groove, the protrusion ensures that the guide shaft slides at an angle in the reciprocating guide groove after each time it passes the protrusion, avoiding backsliding. When it slides onto the protrusion, the compressed spring pushes the inclined guide shaft, and the two sets of inclined guide shafts intersecting enter the corresponding guide groove for guidance, so that the guide shaft smoothly passes the intersection point without jamming. The protrusions at the two corners on one side of the reciprocating guide groove limit the guide shaft, so that the guide cylinder smoothly drives the two sets of laser measuring instruments to complete a 90-degree rotation. The 90-degree rotation process is smooth and without jamming, ensuring that the laser measuring instrument has the same posture before and after rotation, fundamentally eliminating the measurement error caused by lens shake.

[0014] 3. When the switching lever moves with the disc, the racks at both ends mesh with the gear rings on the outer side of the ratchet. The racks drive the ratchet housing to rotate. While the ratchet housing rotates, the inner gear, the rotating shaft, and the connecting frame remain stationary. After the switching lever drives the two sets of laser measuring instruments to rotate 90 degrees, it moves back. Since the ratchet is a unidirectional rotation device, it drives the connecting frame to swing the vacuum cleaner to the lens position of the laser measuring instrument for cleaning. During the return stroke, the torsion spring drives the connecting frame and the vacuum cleaner to reset. The lens is automatically cleaned while rotating, requiring no additional power. This prevents iron filings and dust from adhering to the lens and affecting the acquisition of laser reflection signals, ensuring the stability and reliability of long-term measurements.

[0019] Please see Figures 1-9An embodiment of the present invention provides a transformer core spacing process inspection device, comprising an inspection frame 1, an electric gantry frame 2 mounted on the upper end of the workbench of the inspection frame 1, a telescopic mechanism 3 mounted on the electric gantry frame 2, two sets of cleaning mechanisms 4 mounted on the electric gantry frame 2, an iron core 5 mounted on the workbench of the inspection frame 1, the telescopic mechanism 3 including a hydraulic cylinder 31 fixedly mounted on the lifting frame of the electric gantry frame 2, a sleeve 32 fixedly mounted at one end of the lifting frame of the electric gantry frame 2, an installation cylinder 33 fixedly mounted on one side of the sleeve 32, a drive rod 34 movably mounted inside the sleeve 32 and the installation cylinder 33, a circular piece 35 fixedly mounted at one end of the drive rod 34 at the position of the installation cylinder 33, and a circular piece 35 fixedly mounted on both the upper and lower sides of the circular piece 35. A switching rod 36 is provided, and a stabilizing component 37 is provided on each of the two sets of switching rods 36. A guide cylinder 38 is movably provided inside the mounting cylinder 33. A mounting frame 39 is fixedly provided at one end of the guide cylinder 38. Two sets of laser measuring instruments 310 are fixedly provided on the mounting frame 39. Movable openings 311 are provided on the upper and lower sides of the mounting cylinder 33 corresponding to the positions of the switching rod 36 and the stabilizing component 37. A spring 312 is fixedly provided between the circular plate 35 and the inner wall of the guide cylinder 38. A reciprocating guide groove 313 is provided on the upper and lower sides of the guide cylinder 38. A protrusion 314 is provided at the intersection position in the middle of the reciprocating guide groove 313. A guide groove 315 is provided on the inner side of the protrusion 314. A protrusion 316 is provided at the two corner positions on one side of the reciprocating guide groove 313.

[0020] The hydraulic cylinder 31 telescopic rod is fixedly connected to the drive rod 34. The circular plate 35 and the switching rod 36 are connected at the corresponding movable port 311. One side of the guide cylinder 38 passes through the inside of the mounting cylinder 33 and is connected to the mounting frame 39. The two sets of laser measuring instruments 310 are set in a mirror symmetrical manner. The convex plate 314 and the two sets of convex plates 314 are set to protrude in the reciprocating guide groove 313.

[0021] Furthermore, the electric gantry 2 drives the lifting frame to move downward, so that the telescopic mechanism 3 is aligned with the window of the iron core 5, and then enters the iron core 5. The inner wall of the iron core 5 is inspected by two sets of laser measuring instruments. After passing through the iron core 5, the hydraulic cylinder 31 pushes the drive rod 34 to move axially along the sleeve 32 and the mounting cylinder 33. The drive rod 34 drives the disc 35 to move forward. The disc 35 drives the switching rod 36 to slide in the direction of the movable port 311 on the mounting cylinder 33, while compressing the spring 312. The guide shaft 372 slides in the reciprocating guide groove 313, thereby rotating the guide cylinder 38, the mounting frame 39, and the laser measuring instrument 310 by 90 degrees. The synchronous measurement of the distance between the inner walls on both sides of the window can be completed in one insertion, avoiding the reference conversion error caused by the successive measurement on one side. The two sets of laser measuring instruments 310 are arranged symmetrically in mirrors, and the data on both sides are in the same coordinate system and can be directly compared, which significantly improves efficiency and consistency.

[0022] The stabilizing component 37 includes a circular groove 371 formed inside the switching rod 36. A guide shaft 372 is movably arranged inside the circular groove 371. A spring 373 is fixedly arranged between the guide shaft 372 and the inner wall of the circular groove 371. Four sets of circular grooves 374 are formed inside the lower side of the guide shaft 372. An inclined guide shaft 375 is movably arranged inside each of the four sets of circular grooves 374. A spring 376 is fixedly arranged between the inclined guide shaft 375 and the inner wall of the circular groove 374.

[0023] The guide shaft 372 is inserted into the reciprocating guide groove 313 and is adapted to it. The four sets of inclined guide shafts 375 are arranged crosswise on the lower side, corresponding to the crosswise guide grooves 315. The second spring 376 is in a compressed state.

[0024] Furthermore, when the guide shaft 372 passes the protrusion 316 at the intersection of the reciprocating guide groove 313, the protrusion 316 ensures that the guide shaft 372 slides at an angle in the reciprocating guide groove 313 after each time it passes the protrusion 316, avoiding backsliding. When it slides onto the protrusion 314, the compressed spring 376 pushes the inclined guide shaft 375, and the two sets of inclined guide shafts 375, which are intersected, enter the corresponding guide groove 315 for guidance, so that the guide shaft 372 smoothly passes the intersection point along the guide groove 315 without jamming. The protrusion 316 at the two corners on one side of the reciprocating guide groove 313 limits the guide shaft 372, so that the guide cylinder 38 smoothly drives the two sets of laser measuring instruments 310 to complete a 90-degree rotation. The 90-degree rotation process is smooth and without jamming, ensuring that the laser measuring instrument 310 has the same posture before and after rotation, fundamentally eliminating the measurement error caused by lens shake.

[0025] The cleaning mechanism 4 includes two sets of fixing blocks 41 fixedly installed on the same side of the mounting cylinder 33 at the upper and lower positions. The inner side of each set of fixing blocks 41 is equipped with a rotating shaft 42. The outer side of each set of rotating shafts 42 is fixedly equipped with a ratchet 43. The outer side of each set of rotating shafts 42 is fitted with a torsion spring 44. The outer side of each set of rotating shafts 42 is fixedly equipped with a connecting frame 45. The connecting frame 45 is fixedly equipped with a connecting rod 46 on one side. The inner side of the connecting rod 46 is fixedly equipped with a vacuum cleaner 47. The two ends of the switching rod 36 are fixedly equipped with racks 48.

[0026] The two cleaning mechanisms 4 are arranged in a mirror symmetrical manner. The rotating shaft 42 moves through the outer shell of the ratchet 43 and is fixedly connected to the internal gear. The rotating shaft 42 is fixedly connected to the connecting frame 45. The outer shell of the ratchet 43 is fixedly provided with a gear ring. The outer gear ring of the ratchet 43 is adapted to the rack 48. The upper and lower ends of the torsion spring 44 are respectively inserted into the fixing block 41 and the connecting frame 45. The vacuum cleaner 47 rotates along the fixed block 41 and corresponds to the position of the laser measuring instrument 310.

[0027] Furthermore, when the switching lever 36 moves with the disc 35, the racks 48 at both ends mesh with the gear rings on the outer side of the ratchet 43. The racks 48 drive the ratchet 43 housing to rotate. While the ratchet 43 housing rotates, the inner gear, rotating shaft 42, and connecting frame 45 remain stationary. After the switching lever 36 drives the two sets of laser measuring instruments 310 to rotate 90 degrees, it moves back. Since the ratchet 43 is unidirectional, it drives the connecting frame 45 to swing the dust collection cylinder 47 to the lens position of the laser measuring instrument 310 via the connecting lever 46 for dust collection and cleaning. During the return stroke, the torsion spring 44 drives the connecting frame 45 and the dust collection cylinder 47 to reset. The lens dust collection is completed automatically while rotating, without the need for additional power. This prevents iron filings and dust from adhering to the lens and affecting the acquisition of laser reflection signals, ensuring the stability and reliability of long-term measurements.

[0028] In this embodiment: During use, the electric gantry 2 drives the lifting frame to move downward, so that the telescopic mechanism 3 is aligned with the window of the iron core 5, and then enters the iron core 5. The inner wall of the iron core 5 is detected by two sets of laser measuring instruments. After passing through the iron core 5, the hydraulic cylinder 31 pushes the drive rod 34 to move axially along the sleeve 32 and the mounting cylinder 33. The drive rod 34 drives the disc 35 to move forward. The disc 35 drives the switching rod 36 to slide in the direction of the movable port 311 on the mounting cylinder 33, while compressing the spring 312. The guide shaft 372 slides in the reciprocating guide groove 313, thereby rotating the guide cylinder 38, the mounting frame 39, and the laser measuring instrument 310 by 90 degrees. The synchronous measurement of the distance between the inner walls on both sides of the window can be completed in one insertion, avoiding the reference conversion error caused by the successive measurement on one side. The two sets of laser measuring instruments 310 are arranged symmetrically in mirror, and the data on both sides are in the same coordinate system and can be directly compared, which significantly improves efficiency and consistency.

[0029] Meanwhile, when the guide shaft 372 passes the protrusion 316 at the intersection of the reciprocating guide groove 313, the protrusion 316 ensures that the guide shaft 372 slides at an angle in the reciprocating guide groove 313 after each time it passes the protrusion 316, avoiding backsliding. When it slides onto the protrusion 314, the compressed spring 376 pushes the inclined guide shaft 375, and the two sets of inclined guide shafts 375, which are intersected, enter the corresponding guide groove 315 for guidance, so that the guide shaft 372 smoothly passes the intersection point along the guide groove 315 without jamming. The protrusions 316 at the two corners on one side of the reciprocating guide groove 313 limit the guide shaft 372, so that the guide cylinder 38 smoothly drives the two sets of laser measuring instruments 310 to complete a 90-degree rotation. The 90-degree rotation process is smooth and without jamming, ensuring that the laser measuring instrument 310 has the same posture before and after rotation, fundamentally eliminating the measurement error caused by lens shake.

[0030] When the switching lever 36 moves with the disc 35, the racks 48 at both ends of the lever 36 mesh with the gear rings on the outer side of the ratchet 43. The racks 48 drive the ratchet 43 housing to rotate. While the ratchet 43 housing rotates, the inner gear, rotating shaft 42, and connecting frame 45 remain stationary. After the switching lever 36 drives the two sets of laser measuring instruments 310 to rotate 90 degrees, it moves back. Since the ratchet 43 is unidirectional, it drives the connecting frame 45 to swing the dust collection cylinder 47 to the lens position of the laser measuring instrument 310 via the connecting lever 46 for dust collection and cleaning. During the return stroke, the torsion spring 44 drives the connecting frame 45 and the dust collection cylinder 47 to reset. The lens dust collection is completed automatically while rotating, without the need for additional power. This prevents iron filings and dust from adhering to the lens and affecting the acquisition of laser reflection signals, ensuring the stability and reliability of long-term measurements.

[0031] The control and connection methods of the electronic devices in this invention are common knowledge in the field, and their working principles are well-known technologies. The appropriate model should be selected according to actual use, and will not be elaborated further here.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
